Question

Вычислите: 2 1/3 + 4 1/10:(2 7/15 - 5/12)× 1 1/4
​

Answer 1

$1) \frac{37}{15} -\frac{5}{12} =\frac{148-25}{60} =\frac{123}{60}$

$2) \frac{41}{10} :\frac{123}{60} =\frac{41}{10} *\frac{60}{123} =\frac{6}{3} =\frac{2}{1}$

$3) \frac{7}{3} +\frac{2}{1} =\frac{7+6}{3} =\frac{13}{3}$

$4) \frac{13}{3} *\frac{11}{4} =\frac{143}{12}$
